What is the growth pattern and size of Onion?
New growth will sprout from the top of the Onion as it grows vertically.

Onion’s native range is the Northern Hemisphere, South America, and Africa.
What are the water needs for Onion

What is the right soil for Onion
Onion loves a well-draining soil. Perlite and vermiculite help with drainage, while coco coir adds organic matter, so a good potting soil mix will have all three. You can improve store-bought soil by adding some perlite to it.
What is the sunlight requirement for Onion
Onion requires abundant, bright, and direct light to thrive. The best placement for this plant is within one foot of a window to ensure it receives enough light. If you live in an area with more extreme weather, such as hot summers or cold winters, you may need to adjust the placement of the plant accordingly. During hot summer months, it is important to place the plant away from full sun, as this can cause the leaves to yellow or burn. During cold winter months, it is best to move the plant closer to the window to take advantage of the extra light that can help it survive. By keeping an eye on the current weather in your area, you can make sure your Shallot is always in the right place to thrive.
What's the right humidity for Onion
No extra humidity is necessary for the Onion. Absorption of water by plants is primarily done through their roots, and soil watering is the most effective method to provide humidity to your plants.
How to fertilize Onion
Repotting the Onion should be done either when it has doubled in size or on a yearly basis, whichever occurs sooner. Fresh potting soil with all the required nutrients, refreshed annually, will provide the plant with all the necessary sustenance, making the use of fertilizer unnecessary. Keep in mind that plants receive their energy from the sun, not fertilizer.
